I'd vote for him. Or Johnny Depp. But Leonardo?!?!?!?! He is waaaaay to girly to play Frank.
“But Leonardo?!?!?!?! He is waaaaay to girly to play Frank”
DiCaprio was far from girly in ‘The Departed’ and did a surprisingly good job in that film IMO, but I’m still not seeing him as Sinatra. However, with Scorsese directing, we have a good chance of getting an honest portrayal of Sinatra. Scorsese is nearing the end of his career, and I don’t see him allowing himself being pushed into making a fluff piece on Sinatra.
Jude Law could pull it off.
